Some AVO Valve Tester related patents
I've found a few previously unknown, at least to me, AVO Valve Tester patents that I wanted to share here for anyone interrested.
The first two, GB399193A & GB433296A, relates to the AVODAPTER - you can find a picture of the AVODAPTER here: http://www.museumoftechnology.org.uk...d.php?key=1033 The next one, GB510098A, relates two the design of the valve panel for the AVO Two Panel Valve Tester and the roller selector switch used in the AVO Valve Testers. The next one, GB735865A, relates to how the wiring is done in the valve panel on the AVO Valve Testers (Mk III, Mk IV, CT160/CT160A and VCM163) to minimise oscillations. The last one, GB556467A, relates to the protective relay used in the AVO Valve Testers. Some of the patents of course have a wider field of use than just the AVO Valve Testers but I found them while looking for AVO Valve Tester related patents.
